This pilot clinical trial studies the side effects of recombinant EphB4-HSA fusion protein before surgery in treating patients with transitional cell carcinoma of the bladder, prostate cancer, or kidney cancer. Recombinant EphB4-HSA fusion protein may block an enzyme needed for tumor cells to multiply and may also prevent the growth of new blood vessels that bring nutrients to the tumor. Giving recombinant EphB4-HSA fusion protein before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
